on which basis does the working of metal detector depend
Answers
The metal detectors are easy to understand and including animation by considering with electric motors.
The metal detectors are placed on the principle of transmitting a magnetic field and signal is depends on the history of transmitted field.
This is not usually taken with several prototypes and built according to the gold on a regular basis.
Metal detectors are used to uncover relics, detect guns, knives and mines that are buried underground. They are used by the military for security purposes.
The principle behind metal detectors is "Use electricity to make magnetism and magnetism to make electricity". It consists of a transmitter coil made of a copper wire which creates a magnetic field around it when electrified.
If the detector is over a metal, the atoms inside the metal are affected by the moving magnetic field which in turn creates some electrical activity in the metal.
This results in the formation of a second magnetic field around the metal which is responsible for triggering the alarm through the electricity created.
